Haven't installed on a 2011 yet but we have on a 2010. We found there were some minor clearence difference related to the intermediate pipe/shielding on 2010's. That was actually addressed for the production units we have in stock, the extra clearance was added. I would assume no issues. We'll take it back for a full refund if there was an issue.

Thanks, that sounds good. I am going to order now to lock in the sale price but I probably won't install it till the spring - my garage is unheated and it is too cold in the Northeast to lay on the floor for half the day
